Founded in 1927, Boston's Wolf, Greenfield & Sacks, P.C. has
grown to be one of the preeminent intellectual property firms in
the Northeast, and has been a fundamental part of some of the most
important IP decisions in history.
A History of IP Expertise
From its beginning, when patent attorney Ezekiel Wolf opened up
shop in Prohibition-era Boston, Wolf Greenfield has attracted
notable clients. In its first decades, clients included famed
electrical engineer Andrew Alford and radio pioneer Reginald
Fessenden. Now, Nobel Prize winners, Fortune 500 companies,
high-tech startups, and major research universities rely on the
firm to protect and enforce their IP rights.
Wolf Greenfield's reputation in IP law carries historical
weight. In 1961, the firm successfully argued Aro Manufacturing
Co. v. Convertible Top, now known as the seminal Supreme Court
case covering the doctrine of permissible repair. A few decades
later, in the much different technological era of 1998, the firm's
lawyers crafted the winning argument in the landmark State
Street case, which set the stage for software patents and the
patentability of business methods. More recently, the firm won the
second longest patent interference proceeding in USPTO history and
the largest jury verdict in a trade secret case in Massachusetts
The firm represents clients large and small in patent litigation
in district courts around the country and on appeal before the
Federal Circuit. In addition, the firm's lawyers are frequently
called upon to represent technology companies in high stakes patent
litigation before the International Trade Commission, where Wolf
Greenfield has an outstanding track record of success. The firm has
achieved successes such as summary judgment of patent invalidity in
the Eastern District of Texas (known as a difficult district in
which to secure such summary judgments) and groundbreaking rulings
on novel issues such as the proper claim construction for mouse
nomenclature in patent claims covering transgenic mice. The firm
also has a long and successful history in post-grant matters before
the Patent Office, and is regularly engaged by clients when the
stakes are high.
Wolf Greenfield attorneys have more than just legal training.
Many are also engineers and scientists, backgrounds necessary to
negotiate the complicated underpinnings of their clients'
inventions or products, which range from a client who invented a
new method of DNA sequencing to another who dreamed up a new water
purification system. Because technical knowledge is often a job
requirement, in 1988, the firm pioneered the first technology
specialist program in Boston. Under this program, the firm hires
those with advanced science or engineering degrees to work at the
firm by day and attend law school at night. The goal is that upon
law school graduation, a well-trained IP attorney will be born.
